 Of the 66 tornadoes, tally with hatch marks how many were:
F0, F1, F2, F3, F4, F5
 Add your totals as shown below into weak, strong, and violent catagories:
 weak (F0 + F1)
 strong (F2 + F3)
 violent (F4 + F5)
 Now calculate what percentage each category represents of the total
number of tornadoes (hint: divide the number in the category by the
total, 66, and multiply by 100).
